I'm 15 haven't had sex and I shaved my penis today so I think I just nicked it while shaving but it's decent size and red it only hurts when I touched it. It only happened today but is there something I should do? Should I try to pop it?

Why would you have anything like a postule? A nick is a cut. You didn't shave your penis. You shaved your pubes. No, don't 'pop it' go to the doctor if you don't know what it is.

Well that's the thing I don't know whether I nicked it but this has never happened before but I did get it the same day as I shaved. Which I do dtart from mid shaft and go down.
